Laser Diagnostic Instruments International Inc develops and manufactures laboratory and field/remote sensing instrumentation for real-time, analytical assessment of organic compounds in various environments. Based on the years of experience, superior skills in photonics and the development of analytical software, high sensitivity instrumentation that is selectivity capable of detecting target substances even in complex mixtures have been developed.LDI3’s lead markets are water-quality analysis (environmental assessment and wastewater monitoring) and process monitoring for refineries, the chemical and water treatment industries.
Laser Diagnostic Instruments International Inc was incorporated to bring the leading-edge laser and fluorescence analysis technology and know-how to the North American marketplace. LDI3 distributes the existing product-line and works with clients to tailor the technology to meet new demands and customer-specific applications. It also maintains a laboratory at its Ottawa location to conduct application-specific development.
Laser Diagnostic Instruments International Inc incorporates the following technologies:
Laser Induced Fluorescence (LIF)
LIF analyzers are based upon the capture and analysis of spectra of fluorescence response, induced in the target object by illumination with monochromatic laser emission at one or more wavelengths. LIF reading is a composite of fluorescence responses of individual compounds present in the target object.
Spectral Fluorescence Signature (SFS)
An SFS is a result of measuring a target’s full-spectrum fluorescent response excited with a set of consequently scanned laser lines. It is recorded as a multi-dimensional matrix of intensity and spectral parameters. Various organic compounds are manifested in such a matrix as specific structural singularities representing the SFS.
Ultra-Sensitive Remote Detection (USRD)
In close cooperation with Passat Limited, LDI³ is developing USRD technology for the remote detection of trace chemicals in real-time. USRD technology will have a “dog’s nose” sensitivity level (0.1-1.0 parts-per-billion) at a distance of up to 5 metres and 100 parts-per-billion at 30 metres.
Differential Optical Absorption Spectroscopy (DOAS)DOAS technology relies on the unique absorption spectrum of a gas when it is illuminated with a reference light source. A light beam passes through a column of gas, specific wavelength-dependent absorption occurs, and the spectrum of absorbed light is recorded and analyzed.
